OpenSUSE 11.0 has been discontinued last July (see announcement
here) so that you will not find any new update from now on. Also check
this page for information about lifetime of OpenSUSE releases. The URL you posted is not valid anymore. You can check it by opening
http://download.opensuse.org/reposit...e.org:/STABLE/ in a new TAB of your current browser and see that directory OpenSUSE 11.0 has been removed. The official oss, non-oss and update repositories are still available on the mirrors, but they will soon moved together with the other
discontinued releases. A new installation or an upgrade to the latest release is strongly advised.
